A kitchen chimney (Kitchen Hood) and an exhaust fan are the most commonly used appliances for cleaning the air in the kitchen. Even if they are used for the same basic purpose, these two units are very different and making a choice between the two has always been a major challenge to many homeowners.
Since we don’t want you to make the wrong decision when choosing the most suitable appliance for your kitchen, we have compiled a detailed guide on how kitchen chimneys and exhaust fans work.
Kitchen Hood vs Exhaust Fan

Kitchen Chimney or Kitchen Hood
In terms of performance, a kitchen hood is the best. A kitchen chimney can be either ductless or ducted. As compared to an exhaust fan, a ductless chimney performs the functions of 8-exhaust fan while a ducted chimney is equal to 15 exhaust fans. This means that kitchen chimneys are highly effective in removal of oil particles, grease and smoke from your kitchen. But, they are very expensive.
Just like exhaust fans, some chimneys are able to replace polluted air with clean air. When preparing spicy foods, grease and oil particles may settle on the cabinets, shelves or the wall which gives them an ugly look. A kitchen chimney ensures that smoke, grease and oily particles do not settle on the walls, shelves or your kitchen cabinets which means that your kitchen will always have a nice look.
What are the benefits of kitchen chimneys?

- Design – One of the major benefits of having a kitchen chimney is that it gives your kitchen a modern look. Most of the chimneys on the market come with advanced features such as LED lamps which enhances the look of your kitchen.
- Easy to use –Once you have installed the chimney, operating it will be very easy since most of them are equipped with automatic features for easier use. For example, some come with auto-sensors, timer, auto clean and other features to enhance convenience.

Disadvantages of kitchen chimneys

- Expensive– In terms of price, a kitchen chimney is very expensive which means that not everyone can afford to buy the appliance. Again, installing a cheaper one is a bad idea since most of them will not last.
- Cleaning– Cleaning a kitchen chimney is not easy since all the smoke, grease, oil particles and other pollutants are absorbed in the filters. This means that cleaning it will require a lot of work and you may also need to buy different cleaning solutions.

Disadvantages of Exhaust Fans
